DESCRIPTION
The T48 Controller accepts signals from a variety of temperature sensors
(thermocouple or RTD elements), precisely displays the process temperature,
and provides an accurate output control signal (time proportional or linear DC)
to maintain the process at the desired temperature. The controller’s
comprehensive yet simple programming allows it to meet a wide variety of
application requirements.
The controller operates in the PID control mode for both heating and cooling,
with on-demand auto-tune, which will establish the tuning constants. The PID
tuning constants may be fine-tuned by the operator at any time and then locked
out from further modification. The controller employs a unique overshoot
suppression feature, which allows the quickest response without excessive
overshoot. The unit can be transferred to operate in the manual mode, providing
the operator with direct control of the output. The controller may also be
programmed to operate in the ON/OFF control mode with adjustable hysteresis.
A second setpoint is available on select models to allow quick selection of a
different setpoint setting.
Dual 4-digit displays allow viewing of the process temperature and setpoint
simultaneously. Front panel indicators inform the operator of the controller and
output status. On many models the main control output and the alarm outputs
are field replaceable.
Optional alarm(s) can be configured to activate according to a variety of actions
(Absolute HI or LO, Deviation HI or LO, Band IN or OUT, and Heater Current
Break) with adjustable hysteresis. A standby feature suppresses the alarm during
power-up until the temperature stabilizes outside the alarm region. The second
alarm can be configured as a secondary PID output (heat/cool applications).
Optional Main Linear DC output (10 V or 20 mA) can be used for control or
temperature re-transmission purposes. Programmable output update time
reduces valve or actuator activity. The output range can be scaled independent
of the input range.
Optional Second Linear DC output (10 V or 20 mA) provides an independent
temperature re-transmission, while the main Linear DC output is being used for
control. The output range can be scaled independent of the input range.
Optional Heater Current Monitor provides a direct readout of process heater
current. An alarm can be programmed to signal when the heater has failed. This
provides early warning of system failure before product quality is affected.

Optional Remote Setpoint input (0/4 to 20 mA) allows for cascade control
loops, where tighter control is required; and allows for remotely driven setpoint
signal from computers or other similar equipment. Straightforward end point
scaling with independent filtering and local/remote transfer option expand the
controller’s flexibility.
The optional RS485 serial communication interface provides two-way
communication between a T48 and other compatible equipment such as a
printer, PLC, HMI, or a host computer. In multipoint applications (up to thirty-
two), the address number of each T48 on the line can be programmed from 0 to
99. Data from the T48 can be interrogated or changed, and alarm output(s) may
be reset by sending the proper command code via serial communications. PC
software, SFCRM, allows for easy configuration of controller parameters.
These settings can be saved to disk for later use or used for multi-controller
down loading. On-line help is provided within the software.
The unit is constructed of a lightweight, high impact plastic case with a tinted
front panel. The front panel meets NEMA 4X/IP65 specifications when properly
installed. Multiple units can be stacked horizontally or vertically. Modern
surface-mount technology, extensive testing, plus high immunity to noise
interference makes the controller extremely reliable in industrial environments.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use the T48 to directly command motors, valves, or other actuators not
equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the controller. An independent and redundant
temperature limit indicator with alarm outputs is strongly recommended.

BASIC OPERATION
The T48 controls a process temperature by measuring the temperature via an
input probe, then calculating a control output power value by use of a modified
PID control algorithm. The unit controls the system with the new output power
value to keep the process temperature at setpoint. The PID control algorithm
incorporates features which provide for high control accuracy and low
temperature overshoot from process disturbances.
FRONT PANEL FEATURES
In the normal operating mode, the unit displays the process temperature
in the upper display. One of the following parameters can be viewed in the
lower display:
- Setpoint
- % Power Output
- Temperature Deviation
- Heater Current
- Temperature symbol (F or C)
- Blank Display
The user scrolls through these parameters by pressing the D button. If
enabled, the control setpoint or power output (manual mode only) can be
directly modified in this mode.
In the normal operating mode, parameters are selected by use of the P button
and modified by use of the UP and DOWN buttons. Parameters are then entered
by the P button, which advances the user to the next parameter. Pressing the D
button immediately returns the controller to the normal operating mode without
changing the currently selected parameter.
HARDWARE FEATURES
A fast 100 msec input sampling rate provides quick controller response to a
process disturbance, thus providing excellent temperature control. Measurement
accuracy of 0.3% of span ±1°C or better, provides close process control
conforming to the desired control setpoint value. The T48 accepts a variety of
both thermocouple and RTD temperature probes. An output board contains the
Main Control output, Alarm 1 output, Alarm 2/Cooling output, and/or Linear
DC output. Since the controller is serviceable from the front of the panel, the
output board (on some models) may be easily changed or replaced without
disturbing the wiring behind the panel. No re-programming is required when
changing or replacing the output board for units without the Linear DC output
option. Units with the linear output option require calibration procedure for the
new linear output.
Low-drift, highly stable circuitry ensures years of reliable and accurate
temperature control. The recommended two year re-calibration interval is easily
accomplished via the programming menu.
REMOTE SETPOINT INPUT
The remote setpoint input facilitates the use of a remote signal to drive the
controller’s setpoint. The remote signal can be scaled independent to that of the
controller’s range. The controller’s response to local/remote setpoint transfers
can be programmed. Also, the remote signal is filtered by use of an adaptive
filter. With this filter, relatively large filtering time constants can be used
without suffering from long settling times. The time constant and filter disable
band are programmable. Additionally, the remote signal can also be velocity
limited (or ramped) to slow the controller’s response to changes in setpoint. This
results in a steady control response with no overshoot.
HEATER CURRENT MONITOR
The T48 provides a direct readout of process heater current. This provides
valuable information regarding single phase heater system integrity. It is
especially useful on extruder and large oven applications where adjacent
controllers mask the effect of a failed heater. The heater break alarm senses two
types of heater system faults:
1) Main control output is “on” and heater current is below alarm value. This
indicates failed heater or failed parts of heater, breaker trip, failed power
control device, etc.
2) Main control output is “off” and heater current is above 10% of alarm value.
This indicates a failed power control device, wiring fault, etc.
LINEAR DC ANALOG OUTPUTS
The Main Linear DC output has independent scaling, programmable output
update time and filter (damping) time. These parameters permit flexibility in
process configuration. The output can be set for 0 to 10 V, 0 to 20 mA or 4 to
20 mA ranges, and can be configured for control or for transmission of
temperature or setpoint values.
A Second Linear DC output is dedicated for retransmission of input
temperature. The output can be scaled and converted independent of the input
and Main Linear DC output. This output is isolated from the input.
SETPOINT FEATURES
The controller setpoint can be protected from out of range values by
programming the setpoint range limit values. Additionally, safeguards from
inadvertent data entry can be programmed.
A second setpoint value can be programmed which can be made active by a
user input and/or through the front panel on selected models.
The setpoint ramp feature ramps the setpoint value at start-up or any time a
setpoint change is made, at a user programmable rate. This feature reduces
thermal shock to the process and helps to minimize temperature overshoot.
INPUT FEATURES
A programmable input filter can be used to stabilize readings from a process
with varying or oscillating temperature characteristics, helping to provide better
temperature control. A programmable temperature shift function can be used to
compensate for probe errors or to have multiple T48 units indicate the same
nominal temperature.
The programmable User Input can be used to control a variety of functions,
such as auto/manual transfer of the controller, reset alarm output(s), transfer to
second setpoint, etc.
OUTPUT FEATURES
Programmable output power limits provide protection for processes where
excessive power can cause damage. Automatic sensor probe break detection,
for fail-safe operation, causes the controller to default to a programmed output
power (upscale or downscale burnout). Programmable output cycle time,
output hysteresis and dampening can reduce output activity without degrading
control accuracy. The main outputs can operate in PID, ON/OFF, or manual
control modes.
CONTROL AND ALARM OUTPUTS
In addition to the Linear DC outputs, there are up to three types of ON/OFF
outputs.These outputs can be relay, logic, or triac for control or alarm purposes.
Relay outputs can switch user applied AC or DC voltages. Logic/SSR drive
outputs supply power to external SSR power units. One Logic/SSR Drive output
can control up to four SSR power units at one time. The Triac output supplies
one Amp of AC current for control of an external AC relay or triac device.
AUTO-TUNE
The T48 has an auto-tune feature which, on demand, automatically
determines the PID control parameters for a particular thermal process. After
completion of auto-tune, the PID parameters are automatically optimized for
that process and loaded into non-volatile memory. The operator may view and
modify the parameters as desired.
Auto-tune may be invoked either at start-up or at setpoint, depending on the
process requirements. An auto-tune programmable dampening factor produces
various levels of process control and response characteristics.
RS485 Communications
The RS485 communications option allows the connection of up to 32 devices
on a single pair of wires with a distance of up to 4,000 feet and a maximum baud
rate of 9600. Since the same pair of wires are used for both transmit and receive,
only one way communication is possible at any given time. The controller has
a programmable response time to allow the host device adequate time to release
the communication line for a transmission.
Selected parameters from the T48 can be interrogated or changed, and alarm
output(s) may be reset by sending the proper command code via serial
communications. It is also possible to invoke Auto-tune through the serial port.
Serial communications used with SFCRM software allows for easy controller
parameter configuration by computer.
HEATING AND COOLING SYSTEMS
The T48 is available with dual outputs to provide heating and cooling to those
processes that require them. For example, many extruder applications require
both heating and cooling to maintain accurate extruder barrel and die
temperatures. The T48 is easily configured for these types of applications.

MULTIPLE UNIT STACKING
The T48 is designed for close spacing of multiple units. Units can be
stacked either horizontally or vertically. For vertical stacking, install the panel
latch with the screws to the sides of the unit. For horizontal stacking, the panel
latch screws should be at the top and bottom of the unit. The minimum spacing
from center line to center line of units is 1.96" (49.8 mm). This spacing is the
same for vertical or horizontal stacking.
Note: When stacking units, provide adequate panel ventilation to ensure that
the maximum operating temperature range is not exceeded.

ACCESSORY - EXTERNAL SSR POWER UNIT
The external SSR Power Unit is used with T48s equipped with Logic/SSR
Drive outputs to switch loads up to 240 VAC @ 45 Amps, 25°C ambient. The
unit is operated by applying a low level DC control signal to the isolated
input. The unit features zero cross detection circuits which reduces radiated
RFI when switching load currents. With no contacts to wear out, the SSR
Power Unit provides virtually limitless operational life. The unit is supplied
with an integral heat sink for immediate installation.
External SSR Power Unit:
Part Number: RLY50000
Switched Voltage Range: 50 to 280 VAC
Load Current: 45 Amps max. @ 25°C ambient temperature
35 Amps max. @ 50°C ambient temperature
On State Input: 3 to 32 VDC @ 1500 Ω impedance. (isolated)
(Use Logic/SSR drive output.)
Off State Input: 0.0 to 1.0 VDC

MULTIPLE UNIT/REMOTE SETPOINT APPLICATION
Eight T48 controllers are used in a drying oven. Each T48 controls a zone
within the oven. Depending upon the material to be dried, and its initial
moisture content, the drying setpoint temperature varies. A master T48
controller transmits setpoint via linear DC output. This signal is received as
a remote setpoint signal by the other slave controllers.
Whenever the master controller’s setpoint is changed, the slave controller’s
setpoint changes automatically.
The remote setpoint input at each slave controller can be scaled
independently.

OEM PAINT SPRAYER APPLICATION
An OEM manufacturing spray painting equipment utilizes
the T48 to maintain optimum paint temperature. In addition to
the low cost, the 1/16 DIN package size permits the OEM to
design temperature control into various sized painting
equipment, from small hand sprayers to large paint booths. The
heating element used to heat the paint, is connected to the Main
Control Output (OP1) programmed for On/Off control. Alarm 1
is programmed as Band Inside Acting, so that as long as the
paint temperature is within manufacturer’s specifications for
temperature, the “GO” light is on. Alarm 2 is programmed as
Band Outside acting so that the “NO GO” light is lit when the
paint temperature is more than 12° outside the manufacturer’s
specifications of 140 to 150°F.

PLASTICS EXTRUDER APPLICATION
Several T48 controllers are employed to control the
temperature of a plastics extruder. Each T48 controls a
heating element and a cooling water solenoid to maintain
each extruder zone at the desired temperature. The Heater
Current Monitor option is used to provide a readout of the
heater current. The multi-function User Input can be
programmed to allow selection of manual operation when
connected to common. This allows the user to hold the
control output of the controller during abnormal process
conditions.
